Discovering working but not the example

[davidaparicio]

Hi @cescoffier !

The example is working well in my local machine. Before to test to Kubernetes (Google Compute Engine), I made containers and I launched, locally, them with docker-compose. The logs and the discovery page seem everything is working well but the main application doesn't work.... Do you have a idea, why is it not working ? Because unfortunately, I have any clue..

The discovery page:

The docker-compose log, and Hazelcast discovery:

Finally the circuit-breaker:

Best regards, David

You can find the code in my repository: https://github.com/davidaparicio/vertx-microservices-examples

Hi, yes, I think I have an idea.

The service are exposed on localhost:808x, which in your environment may be an issue because they are not deployed on the same machine.

[davidaparicio]

So true, I have not even seen this ineptitude -_-'

Now, I have a question about the same system under Kubernetes.. I think this system of Discover is the best way to communicate between containers/hosts on the cloud (like Google Compute Engine). It is the same like Openshift ? (:

Because, my last step will be to use Kubernetes Cluster Federation ^^

[cescoffier]

We provide an extension to the discovery service to use Kubernetes services and import them "automatically" - check http://vertx.io/docs/vertx-service-discovery-bridge-kubernetes/java/

With this bridge, you don't have to publish your services as you need to declare them into Kubernetes. The bridge will then retrieve the services from Kubernetes.

Hi @cescoffier !

I followed the "Run the demos in Openshift Origin (v3)" chapter

Instead of

docker rm origin
sudo docker run -d --name "origin" \
        --privileged --pid=host --net=host \
        -v /:/rootfs:ro -v /var/run:/var/run:rw -v /sys:/sys -v /var/lib/docker:/var/lib/docker:rw \
        -v /var/lib/origin/openshift.local.volumes:/var/lib/origin/openshift.local.volumes \
        openshift/origin start
docker logs -f origin

I used jimmidyson/minishift

I run mvn clean package docker:build fabric8:json fabric8:apply -Popenshift without problem.

The dashboard is in the same as yours (I grouped A and B only for the screenshot)

But the discovery isn't working (bug with Kubernetes)

SEVERE: Error while interacting with kubernetes

What I have to do to resolve this?

Annexe: I tested the service (like, http://c-vertx-microservice-example-aggregation-http.192.168.99.102.xip.io/?name=test it's working).

[cescoffier]

You need to add slf4j-api as a dependency to all projects.

Okay, thanks a lot @cescoffier !!
